Blanfordia simplex is a species of land snail that has an operculum, a terrestrial gastropod mollusk in the family Pomatiopsidae.
Henry Augustus Pilsbry described it as Blanfordia japonica var. simplex in 1902. He has elevated this taxon to specific level in 1903.Pilsbry H. A. & Hirase Y. (1903). "New land shell of the Japanese Empire". The Nautilus 16: 114-117.
Distribution This species is endemic to Japan.Kameda Y. & Kato M. (2011). "Terrestrial invasion of pomatiopsid gastropods in the heavy-snow region of the Japanese Archipelago". BMC Evolutionary Biology 11: 118. . It occurs widely along the Sea of Japan. The type locality is Nishigo, Uzen Province, Honshu.
It is a Near Threatened species. "ヒメオカマメタニシ" . 日本のレッドデータ検索システム [Japanese Red List Data Book], accessed 17 July 2011.
Description Blanfordia simplex has a shell with 4.1-5.1 whorls. Pilsbry (1902) described the first whorl to be more or less worn. The color of the shell is yellowish-olivaceous. It has the lip hardly visible, only a mere trifle expanded.
The width of the shell is 3.7-4.2 mm. The height of the shell is 5.9-6.9 mm.
